Step 1

Bring a large pot of salted water to the boil for the pasta and add the spaghetti. Heat a large frypan over medium heat and add the oil. Add the cauliflower and season well with salt. Fry, stirring occasionally, until well browned. Turn off the heat but leave the cauliflower in the hot pan.

Step 2

When the spaghetti is al dente, add it to the cauliflower with about ½ a cup of the pasta water. Add the ricotta, parmesan, lemon zest and juice and parsley and toss everything together until the ricotta and parmesan form a creamy sauce. Season well with black pepper, then serve with extra parmesan.
